Question
The table below shows the number of hours per day 11 patients suffered from headaches before and after 7 weeks of soft tissue therapy. At a 0.01, is there enough evidence to conclude that soft tissue therapy helps to reduce the length of time patients suffer from headaches? Assume the samples are random and dependent, and the population is normally distributed. Complete parts (a) through (). Patient Dally headache hours (before) 2.9 3.2 3.4 1.8 4.4 1.8 3.8 2.5 1.8 3.3 3.8 Dally headache hours (after) 1.7 3.6 2.2 1.1 1.1 1.4 3.5 22 1.2 2.9 4.3 1 2 3 456 789 10 11 D OD. Ho: H20 OE Ho He =d OF. Ho: Hyzd (b) Find the critical value(s) and identify the rejection region(s). 6-2.764 (Use a comma to separate answers as needed. Type an integer or a decimal. Round to three decimal places as needed.) Identify the rejection region(s). Choose the correct answer below. A. t>2.764 O B. t< -2.764 or t> 2.764 OC. t<-3.169 or t>3.169 O D. t< -3.169 (c) Calculate d d= 0.682 (Type an integer or a decimal. Round to three decimal places as needed.) Calculate s (Type an integer or a decimal. Round to three decimal places as needed.)
